Configure vlan in gbe2c

We've recently bought a c3000 with one gbe2c inside and two servers (480c).The servers aregoing to be on different subnets in the futureand as we use VLAN I thought it would be noproblem as I'm familiar with the switches weuse. (procurve 5300 for routing and 2524 asendswitches)

My config on 2524 is that I have port 1-20on vlan 11 (clients) and port 21-24 on vlan 12 (server/printer) both vlans tagged to fiberports 25-26 going to next switch...Vlan 10 has an ip so I can manage the switch
